Feedback:
With directly observed therapy (DOT), the patient makes periodic visits to the office of the primary health care provider or the health clinic and takes the drug in the presence of the nurse. Nurses watch the patient swallow each dose of the medication treatment. In some cases, the nurse may travel to the patient's home, place of employment, or school to observe or administer medication. DOT can be used during the initial and/or continuation phase of treatment.
Answer to Question 2
Ans: C
Feedback:
Rifampin interacts with oral hypoglycemic agents, leading to a decrease in the effectiveness of the oral hypoglycemic agent, thus increasing blood glucose levels. An increased risk for bleeding occurs when rifampin is given with oral anticoagulants. An increased risk of hepatotoxicity occurs when rifampin is given with isoniazid. When verapamil is given with rifampin, the effectiveness of verapamil is decreased, leading to increased blood pressure levels.
